/**
*
* Generates all possible sentences from the input argument string.
* The string s must follow a special syntax as illustrated in the
* example below:<br/>
* `'[I] [am having|have] [a] [problem|question]'`<br/>
*
* Each phrase must be quoted between `[ ]` and each possible option of phrases
* (if any) must be separated by a `|` character. The corpus is composed by
* computing the cartesian product of all the phrases.
*
* @alias string#composeCorpus
* @param {string} str the input string.
* @return {string[]} of all possible sentences.
* @example
* composeCorpus( '[I] [am having|have] [a] [problem|question]' );
* // -> [ 'I am having a problem',
* // 'I am having a question',
* // 'I have a problem',
* // 'I have a question' ]
