made metakernel installable

parent fff3efd0
**MetaKernel Echo** is a Jupyter kernel using MetaKernel magics, shell, help, and parallel processing tools. This code provides an example MetaKernel kernel.
## Install
First, you need to install the metakernel_echo library and dependencies:
pip install metakernel_echo --upgrade
Then, you need to install the metakernel echo kernel spec:
python metakernel_echo install
## Running
You can then run the metakernel_echo kernel as a console, notebook, etc.:
jupyter console --kernel=metakernel_echo
## Dependencies
1. IPython 3
1. MetaKernel (installed with pip)
