Add Support for List of Tag Maps (#18)
* Updated to not used null_resource so that the null_resource provider isn't required * Updated to unclude the null provider version. Updated to allow for tagging of Autoscaling groups. It was really damn hard guys, really hard to getthat stupid thing expanding as a dynamic list. * updated formatting * Fixed up readme. added better example. Added commends. Added contributor section. fixed copy paste error in table. * Clarified and tested the usage of the tags * Updated the path to the module in the example * fixed formt * made module generic * made module generic * Fixed up the autoscaling group example to be very clear with many comments. * updated example in README * fixed formatting * changed example resource names from 'this' to 'default' * remove provider * Updated for consistency with other modules, fixed typoes * Updated variable description
