Compilation errors and allowing meters grid

[uashrani]

My compiler was having a few compilation errors, so I changed the following things

• In the Config file, it was not recognizing comments, so I changed the code to skip lines beginning with #
• parameters.cpp was expecting more inputs/parameters than the Config file gave (e.g. runoff ratio), so the Config file now specifies these
• The compiler also gave a redundancy error about variables' shared or private status in dephier.hpp, so I removed the default(none)

Also, I allowed the inputs to be in a meters grid so latlon is not required anymore, and changed the cell size calculation accordingly
