+/*
+ * IMCE Integration by URL
+ * Ex-1: http://example.com/imce?app=XEditor|url@urlFieldId|width@widthFieldId|height@heightFieldId
+ * Creates "Insert file" operation tab, which fills the specified fields with url, width, height properties
+ * of the selected file in the parent window
+ * Ex-2: http://example.com/imce?app=XEditor|sendto@functionName
+ * "Insert file" operation calls parent window's functionName(file, imceWindow)
+ * Ex-3: http://example.com/imce?app=XEditor|imceload@functionName
+ * Parent window's functionName(imceWindow) is called as soon as IMCE UI is ready. Send to operation
+ * needs to be set manually. See imce.setSendTo() method in imce.js
