Selects the nearest word to an input out of a set of options

1	MultipleChoice(x,y,tvectors=tvectors,breakdown=TRUE)

`x`	a character vector of `length(x) = 1` specifying a sentence/ document (or also a single word)
`y`	a character vector specifying multiple answer options
`tvectors`	the semantic space in which the computation is to be done (a numeric matrix where every row is a word vector)
`breakdown`	if `TRUE`, the function `breakdown` is applied to the input

Computes all the cosines between a given sentence/document or word and multiple answer options. Then selects the nearest option to the input (the option with the highest cosine).This function relies entirely on the costring function.
A warning message will be displayed if all words of one answer alternative are not found in the semantic space.
