Function calculateIndexScore

Recursive function that calculates the score of a formData against the given schema. The computation is fairly simple. Initially the total score is 0. When schema.properties object exists, then all the key/value pairs within the object are processed as follows after obtaining the formValue from formData using the key:

• If the value contains a oneOf and there is a formValue, then score based on the index returned from calling getClosestMatchingOption() of that oneOf.
• If the type of the value is 'object', calculateIndexScore() is called recursively with the formValue and the value itself as the sub-schema, and the score is added to the total.
• If the type of the value matches the guessed-type of the formValue, the score is incremented by 1, UNLESS the value has a default or const. In those case, if the default or const and the formValue match, the score is incremented by another 1 otherwise it is decremented by 1.
