added capability to turn xml into json for material purposes. this will assist
because I have some xml materials already written that need to be written in
json. removed extraneous old functions.
nea specification finished. it will require an update to the spec language and
translation, allowing for cycle lengths in EFPD and capacity factors. the nea
and inpro files have been moved to their own input directories. an enrichment
fab has been added to the nea spec, which was missing from the original document
(i.e., it names the facility connection and output information, but doesn't
specify its parameters).
defines the spec for the first nea scenario and adds some helper scripts for moving from xml to json
