/**
 * Acts like native Module.component() function but merging component options
 * with parent component options. This method establishes the $options property
 * to the component controller class with the merged component options. To
 * retrieve parent options, it reads the same property of the parent class, so
 * for the parent options to be copied, it must have been declared using this
 * same function. If any of the options (template, transclude, bindings...) is
 * redeclared in the child component, the last has preference.
 *
 * @param {String} name Coponent name in camelCase
 * @param {Object} options The component options
 * @return {angularModule} The same angular module
