Issue triggering Typescript functions with no specified return type

[marshallmick007]

DocStubsJS doesn't seem to like to be triggered if there is a typescript function with no specified return type:

/** (nothing happens)
doSomework = (arg: string) => {

}

If a return type for the function is specified, then the comment block gets generated properly

/**
 *
 **/
doSomework = (arg: string) : void => {

}
