New Revision: 10429

URL: http://svn.gna.org/viewcvs/relax?rev=10429&view=rev
Log:
An additional function is added, that converts a string (such as 'xxx * e-1') 
into a float. 

This convert_string_to_float_patch file was attached to 
https://gna.org/task/?6847 by Michael
Bieri (https://gna.org/users/michaelbieri), in the zip file 
calc_modelfree.py_patch.tar.gz
(https://gna.org/support/download.php?file_id=7750).

This function is used to read in bond length or csa values set in settings 
window as float values.

The following changes were made to the patch:
    converttofloat was renamed to convert_to_float to match relax' standards,
    ''' was replaced with """ (again a relax standard),
    The single space at the start of the docstring header line was removed 
and a full stop added
        (both are needed to meet the standard),
    The docstring expanded,
    Comments were added and the lines with '######################' removed.
