Get Spelling Suggestions JSON

Get spelling suggestions for a given term (the name parameter). The suggestions are terms contained in the current version of the RxNorm data set, listed in decreasing order of closeness to the original phrase. getSpellingSuggestions is not ideal for finding all extensions of a given stem (such as to suggest complete drug names as someone begins to type on a web form). Instead, consider getDisplayTerms.
