code: function uint (type) {
    type === 'uint' ? 'uint256' : type
    var storageBytes = parseInt(type.replace('uint', '')) / 8
    return new UintType(storageBytes)
  }
docs: Uint decode the given @arg type
  
  @param {String} type - type given by the AST (e.g uint256, uint32)
  @return {Object} returns decoded info about the current type: { storageBytes, typeName}
