@yeze322 Added couple of methods:

1. copyTemplate(content: string, fromTemplateName: string, toTemplateName?: string): string 

2. removeTemplates(content: string, templateNames: string[]): string

// if Name exist, throw error.
3. addTemplate(content: string, { Name, Parameters, Body }: Template): string

// if Name exist, add it anyway, with name like `${Name}1` `${Name}2`
4. addTemplateAnyway(
  content: string,
  { Name = 'TemplateName', Parameters = [], Body = '-TemplateBody' }: Template
): string

and applied to visual editor ObiEditor.tsx, please review~

copyTemplate is good enough for visual editor to use!

Looks good, and can you add those signature into comments of code at somewhere?

Yes, added to lgUtils.ts

@boydc2014 can it be merged?

[boydc2014]

Looks good.

[boydc2014]

FYI, @cwhitten , I merged this, since it's most additive and it's a blocker for @yeze322's work of LG copy\delete.
