Generate a list of all the terms that appear in a .json file
**Parameters**
filename: *str*
The name of the .json file to be input.
term_filter: *str*
The type of filter to be used for parsing through all the words in
the Tweets. There are six different filters that can be used:
default - considers all of the terms
remove_stop_words - does not consider stop-words
hashtags - only considers hashtags and no other terms
terms_only - does not consider hashtags or mentions
single_terms - only counts terms once in a Tweet
single_stop_words - only counts terms once and does not
consider stop-words
**Returns**
terms: *list, str*
A list with all of the individual terms that appear in the .json
file.
