[svn-r14948] Add a test for the floating point user defined printf format

Usage is 

-m T, --format=T

Where T - is a string containing the floating point format, e.g '%.3f'

The test consists of writing a number with 7 fractional digits (default precision display of %f is 6 digits) and have the 7 digits displayed with 

-m %.7f fpformat.h5

Tested: windows, linux, solaris

Note: the output file was generated in linux, it may be possible that platforms other than the ones tested have a different representation of the number
