Updated add_field function. It is now possible to give a structure as input.
For instance, if there is a json object that contains attr1.attr2.attr3, then we can call this function with that json object, the value and "attr1.attr4". This will create a new attribute on the same level as attr3 with the specified value.
sloppy fix in inserting stream

Added rm_field function. Also restructured a bit in the file.
Added so that the make docs command also compiles the files, only the most recent compiled code is generated for the documentation.
Renamed the function in lib_json, so the places it was used needed to be renamed aswell.
Added proper and more detailed documentation. Generate the documentation with 'make docs' and take a look.
