'''

Goes though all go files in the tree and looks for copy-paste dirt : 
command line args:
-s:<path>               -   path to recursively scan *.go files 



Working example:

in the zabo-api-provider-gemini/
(and assuming there is a folder zabo-api-provider-bittrex/ 

func (c *Controller) GetTransactionsPage(context *zaboutils.ExtendedContext, account *zaboresources.Account, cursor *string) ([]*zaboresources.AccountTransactionRes, *string, bool, *echo.HTTPError) {
...
	c.logger.LogWithContextf(zaboutils.Severity.INFO, context, zaboutils.FuncName(c.GetBalance), "Next cursor is %v", "Bittrex")
...
}

-- this should issue a warning as the word bittrex is out of context
