/** Standardised data schema's for IoT Home Automation

/** network table
* A table of network devices (logical and physical)
* This schema uses a structure suitable for use with VueJS/bootstrap-vue `b-table` options.
* The table is an object of objects with the ID as the primary key
* It is periodically updated by an NMAP scan.
* The hostname, dhcp and description fields can be update from a uibuilder front-end.
