Fixed formatting in informational output message
Added information on doxypy dependency necessary for running Doxygen
Fixed bug where default isohyet map was based on zero map instead of
a map with values of onehundred.  When the zero map was used, there would
be no precipitation in a model, instead, by default when isohyet map is
specified, precipitation should be scaled by 1.0 (i.e. no scaling)
Upped version number for 1.11 release
