+cose-base
+================================================================================
+
+## Description
+
+This is a core module for compound spring embedder based layout styles such as CoSE-Bilkent, fCoSE, and CiSE.
+
+## Dependencies
+
+ * layout-base ^1.0.0
+
+## Usage instructions
+
+Add `cose-base` as a dependecy to your layout extension.
+
+`require()` in the extension to reach functionality:
+
+ * `var CoSEConstants = require('cose-base').CoSEConstants`,
+ * `var CoSELayout = require('cose-base').CoSELayout`,
+ * `...`
+
+To reach functionality of `layout-base`:
+
+ * `var Integer = require('cose-base').layoutBase.Integer`,
+ * `var Layout = require('cose-base').layoutBase.Layout`,
+ * `...`
