This constructor function converts a character vector into an
EprimeFrame object, which is just a list with some special metadata
values. Strings with the format "key: value" are parsed into key
= value list items (via listify).
EprimeFrame(keys_values)
| keys_values | a character vector of containing some |

a list with the class EprimeFrame and with special
Eprime. metadata, Running and Procedure values, all
set to NA by default.
