v1.7.0 build

I have never head of \l and MSVC warns about unknown escape sequence, so
I changed it into \f that definitely exists and potentially might be
useful.

+Do note that "overly complex" expressions cannot be decomposed and thus will not compile. This is done partly for practical reasons (to keep the underlying expression template machinery to minimum) and partly for philosophical reasons (assertions should be simple and deterministic).
+
+Examples:
+* `CHECK(a == 1 && b == 2);`
+This expression is too complex because of the `&&` operator. If you want to check that 2 or more properties hold, you can either put the expression into parenthesis, which stops decomposition from working, or you need to decompose the expression into two assertions: `CHECK( a == 1 ); CHECK( b == 2);`
+* `CHECK( a == 2 || b == 1 );`
+This expression is too complex because of the `||` operator. If you want to check that one of several properties hold, you can put the expression into parenthesis (unlike with `&&`, expression decomposition into several `CHECK`s is not possible).

+
+To limit execution to a specific section within a test case, use this option one or more times.
+To narrow to sub-sections use multiple instances, where each subsequent instance specifies a deeper nesting level.
+
+E.g. if you have:
+
+<pre>
+TEST_CASE( "Test" ) {
+  SECTION( "sa" ) {
+    SECTION( "sb" ) {
+      /*...*/

+Then you can run `sb` with:
+<pre>./MyExe Test -c sa -c sb</pre>

+<pre>./MyExe Test -c sd</pre>
+
+To run all of `sa`, including `sb` and `sc` use:
+<pre>./MyExe Test -c sa</pre>
+
+There are some limitations of this feature to be aware of:
+- Code outside of sections being skipped will still be executed - e.g. any set-up code in the TEST_CASE before the
+start of the first section.</br>
+- At time of writing, wildcards are not supported in section names.
+- If you specify a section without narrowing to a test case first then all test cases will be executed 
+(but only matching sections within them).

+
+When this option is used then every test is given an additional tag which is formed of the unqualified 
+filename it is found in, with any extension stripped, prefixed with the `#` character.
+
+So, for example,  tests within the file `~\Dev\MyProject\Ferrets.cpp` would be tagged `[#Ferrets]`.

 Catch has some basic compiler detection that will attempt to select the appropriate mix of these macros. However being incomplete - and often without access to the respective compilers - this detection tends to be conservative.
 So overriding control is given to the user. If a compiler supports a feature (and Catch does not already detect it) then one or more of these may be defined to enable it (or suppress it, in some cases). If you do do this please raise an issue, specifying your compiler version (ideally with an idea of how to detect it) and stating that it has such support.

+
+### Features/ Changes:
+* Catch now runs significantly faster for passing tests
+  * Microbenchmark focused on Catch's overhead went from ~3.4s to ~0.7s.
+  * Real world test using [JSON for Modern C++](https://github.com/nlohmann/json)'s test suite went from ~6m 25s to ~4m 14s.
+* Catch can now run specific sections within test cases.
+  * For now the support is only basic (no wildcards or tags), for details see the [documentation](docs/command-line.md).
+* Catch now supports SEH on Windows as well as signals on Linux.
+  * After receiving a signal, Catch reports failing assertion and then passes the signal onto the previous handler.
+* Approx can be used to compare values against strong typedefs (available in C++11 mode only).
+  * Strong typedefs mean types that are explicitly convertible to double.
+* CHECK macro no longer stops executing section if an exception happens.
+* Certain characters (space, tab, etc) are now pretty printed.
+  * This means that a `char c = ' '; REQUIRE(c == '\t');` would be printed as `' ' == '\t'`, instead of ` == 9`.
+
+### Fixes:
+* Text formatting no longer attempts to access out-of-bounds characters under certain conditions.
+* THROW family of assertions no longer trigger `-Wunused-value` on expressions containing explicit cast.
+* Breaking into debugger under OS X works again and no longer required `DEBUG` to be defined.
+* Compilation no longer breaks under certain compiler if a lambda is used inside assertion macro.
+
+### Other:
+* Catch's CMakeLists now defines install command.
+* Catch's CMakeLists now generates projects with warnings enabled.
