This script detects a Raspberry Pi's model, manufacturer and mb ram, based
on the cpu revision number. Data source:
http://elinux.org/RPi_HardwareHistory
You can instantiate the ModelInfo class either with a parameter `rev_hex`
(eg. `m = ModelInfo("000f")`), or without a parameter
(eg. `m = ModelInfo()`) in which case it will try to detect it via
`/proc/cpuinfo`. Accessible attributes:
class ModelInfo:
model = '' # 'A' or 'B'
revision = '' # '1.0' or '2.0'
ram_mb = 0 # integer value representing ram in mb
maker = '' # manufacturer (eg. 'Qisda')
info = '' # additional info (eg. 'D14' removed)
