Generate a CPP struct for the given 'struct_node'. Children nodes of the
'struct_node' must have a 'type' child associated with it.

symbol: {type: string},
name: {type: string},
market_cap_rank: {type: u16},
market_data: {type: INS_CoinGecko_CoinMarketData},

name: The name of the enum to generate
Input: (With name = "INS_QueryType", required_tag = "json_endpoint")

Generate ImGui widgets for visualising the given 'struct_node'. If a custom type
is provided, we assume that an ImGui function has been previously generated for
the type already.

Generate for any root MetaDesk node tagged with 'json_endpoint'. The MetaDesk
node containing the 'json_endpoint' can specify fields that the JSON parsing
function will attempt to pull out from the provided JSON string, powered by the
