Various regex failures (older GCC)

The GIS tools use std::regex, but these are flakey (really bad) on older versions of gcc.

changed title from Failure regx of GCC to Various regex failures (older GCC)

changed the description

Should either use the OpenFOAM wrapped version (regExp), or simply split the input string on spaces, check the key/value and process from there. But not for this release!

@matti - the regex used match key,value without any spaces in between (if I remember correctly). Not sure if this is correct, or sloppy.

Would be helpful to at least have a small comment like:

// Parsing stuff that looks like this:
// ncol<INT>
// ...

in the code - lets people know what is going on without digging through other docs.

@Prashant and @PraveenJaganthan - ignore test failures for older GCC (eg, less than gcc-6) on this module.
