Following Changes Have been made:
1. Rename KMAP -> SPECIAL_KEYS
2. Added Default Mappings through KEY_MAPPINGS
so when the config is read it will change the KEY_MAPPINGS map
which will be then used by the handler function for events.
Following Changes have been made in addition to
`1572a460b0`
1. config.go :
ReadMappings Reads Array for each function
Basically we are going to define mappings like this :
```yml
Function :
- first mapping
- second mapping
- third mapping
`````
2. kMap.go :
GetAsciiValues will help us to get e.Rune() for the event for
the handler function. So basically we will have a keymappings map
generated which will help us to handle events.
for e.g
if an user has defined following mappings
````yml
togglePlayBack :
- P
- p
- B
````
then the keymappings map will look like this
[]keymappings = {
GetAsciiValues("P") : togglePlayBack(),
GetAsciiValues("p") : togglePlayBack(),
GetAsciiValues("B") : togglePlayBack(),
}
so when the handler function will get an event e
we will just pass it to this keymappings map i.e
keymappings[e] which will return the function
